Best time to visit in

Sri Lanka

Weather & Temperature

Hot and humid island-wide (26–34°C day; 22–26°C night). April sees short, intense inter‑monsoon thunderstorms. Southwest monsoon settles in by May–June, bringing frequent rain and rougher seas to Colombo, Galle, the south/west coasts and hill country, while the north and east (Trincomalee, Passikudah, Arugam Bay) turn sunny and drier. Visibility for diving improves on the east; leeches appear on wet trails in tea country.

What to Expect

Fewer international crowds and better hotel deals in the southwest; lively local travel around mid‑April New Year. Expect quick downpours in the west/south and clearer, beach‑friendly days on the east coast. Some outdoor plans in the hills may need rain backups.

Key Events & Festivals

• Sinhala & Tamil New Year (Avurudu) – mid‑April
• Vesak Poya (Buddha Jayanti) – May full moon
• Poson Poya – June full moon (Mihintale pilgrimages)

Recommended Activities

• Beach time and snorkeling on the east coast (Trincomalee, Nilaveli, Passikudah)
• Surfing at Arugam Bay (season kick‑off May–June)
• Wildlife safaris at Yala and Udawalawe (good sightings as water sources shrink)
• Cultural Triangle sightseeing (Sigiriya, Polonnaruwa, Anuradhapura) with early starts
• Tea factory tours in Nuwara Eliya and Ella between showers
• Cooking classes and Ayurveda/spa sessions on rainy afternoons

Travel Tips

• Base yourself on the east/north coasts for more sunshine; keep the southwest as short stopovers.
• Pack a light rain jacket, quick‑dry clothes, and waterproof bags for gear.
• Seas can be rough on the south/west—heed lifeguard flags and avoid risky swims.
• Poya (full‑moon) days may bring alcohol sales restrictions and some closures—plan ahead.
• Book trains and intercity buses early around mid‑April due to local holiday rush.
• Carry mosquito repellent; rain increases breeding.
• Indian travelers: no time difference from IST (UTC+5:30); use an ETA/eVisa and check latest rules before travel.
